Transmission Dynamometer.

Friction is only the medium for absorption, and does not enter
into the calculation. The arrangement at K permits adjustment
for various motors.



White's Transmission Dynamometer is represented
in Fig. 597. A is the, motor shaft, and B that of the driven
machine. As A turns left-handed, the arm F E is held back by the
weight E, and thus B is turned to the right. Supposing the arm
were carried round, no work would be given to B, which would be
stationary, but E'S rotations would be half those of A (see fig. 526),
The load supported on A would therefore be half that on E (at
equal radii). But although the power be taken off at B, A and E
have yet the same relation, so that
